Gutting houses is part of the rehab effort in the aftermath of Hurricane Katrina. Today you'll meet locals who volunteered in New Orleans and a victim who was helped.

Genetically designed grapes with elevated levels of vitamin C may be more than wishful thinking, according to researchers at the University of California, Davis, and the University of Adelaide, Australia.
